【発明の属する技術分野】
本発明は誤組付を防止するのに好適な差動装置に関する。
【０００２】
【従来の技術】
四輪車等の車輪間の回転数差を吸収するとともに各車輪へ駆動トルクを配分する差動装置としては、例えば、特表平８−５００６５９号公報「差動機構」が知られている。
【０００３】
上記技術には、同公報の図５に示される通り、駆動力側となる入力ハウジング１１と、この入力ハウジング１１の内周面に設けた複数の溝３９と、入力ハウジング１１の内周側に配置した複数の二種類のカム従動子２８と、これらのカム従動子２８に一体に成形するとともに上記溝３９に嵌合する駆動ドッグ３６と、これらの駆動ドッグ３６のうちの一方の種類のカム従動子２８の駆動ドッグ３６に、他方の種類と識別するために設けた溝３６ａとが記載されている。
入力ハウジング１１内にカム従動子２８を組付ける場合には、駆動ドッグ３６に溝３６ａがあるものとないものとを２つずつ交互に周方向に並べる。
【０００４】
【発明が解決しようとする課題】
上記技術では、入力ハウジング１１内にカム従動子２８を組付ける場合及び組付の確認を行う場合には、溝３６ａの有無を目視でチェックするが、見誤りや見落しが発生して、誤組付することが考えられる。
この対策として、差動機構が完成した後に、全数の作動テストを行って誤組付を確認することも可能であるが、作業工数が増えて、生産性の低下を招くという不都合がある。
【０００５】
そこで、本発明の目的は、誤組付をより確実に防止することができる差動装置を提供することにある。
【０００６】
【課題を解決するための手段】
上記目的を達成するために請求項１は、駆動源に連結したデフケースの回転に伴って円周方向に移動する複数の入力側ブロックと、これらの入力側ブロックを相対滑り可能に挟み込むとともに各ブロックとの摩擦力で独立して回転することで出力側の差動を発生させる２つの出力側カムとを備えた差動装置において、前記入力側ブロックを複数種類で構成し、これらの入力側ブロックに種類に応じて幅を異ならせた凸部を設け、これらの凸部にそれぞれ嵌合する凹部を入力側ブロックの種類に応じて幅が異なるようにデフケース側に設け、複数種類の前記入力側ブロックの一つが、凸部に窪みを備え、この凸部に嵌合する凹部が、窪みに対応する突起を備え、凸部の幅が二種類有り、幅の狭い凸部の先端面に窪みが設けられるとともに、この凸部に嵌合する凹部の底に突起が設けられ、この凸部に嵌合する凹部の幅が、この凹部に他方の凸部を嵌合しようとした場合に、この凹部の底と他方の凸部の先端面との隙間が形成されて凹部の突起が他方の凸部の先端面に干渉しないように、他方の凸部の幅に対して小さく形成されることを特徴とする。
【０００７】
デフケース側に設けた凹部に合致した幅の凸部を有する入力側ブロックはデフケース側に結合させることができる。
デフケース側に設けた凹部に合致しない幅の凸部を有する入力側ブロックはデフケース側に結合させることができない。
従って、デフケース側への入力側ブロックの誤組付を防止することができる。
【０００８】
また、凹部の突起と凸部の窪みとが対応しない、即ち対向しないことも明らかに認識することができ、入力側ブロックの種類に応じて凸部の幅を異ならせたことと合せて二重に誤組付の確認をより確実に行うことができる。

また、軸方向溝７３ｂは溝底に突起７３ｃを備え、凸部７８ａは上面に前述の突起７３ｃに対応する窪み７８ｂを備える。
【００１６】
次に差動装置の入力側ブロックの誤組付について説明する。
図４（ａ），（ｂ）は本発明に係る差動装置の入力側ブロックの誤組付について説明する作用図である。
（ａ）において、本来なら、ケース本体７３の軸方向溝７３ａに入力側ブロック７７の凸部７７ａを嵌合し、ケース本体７３の軸方向溝７３ｂに入力側ブロック７８の凸部７８ａを嵌合しなければならないが、誤って（１）軸方向溝７３ａに入力側ブロック７８の凸部７８ａを嵌合しようとし、また、（２）ケース本体７３の軸方向溝７３ｂに入力側ブロック７７の凸部７７ａを嵌合しようとした場合、（ｂ）に示すように、上記（１）の場合には、入力側ブロック７７の上部幅Ｌ１に対して入力側ブロック７８の上部幅Ｌ２が小さいため、ケース本体７３の軸方向溝７３ａと入力側ブロック７８の凸部７８ａとの間に大きな隙間が生じ、上記（２）の場合には、（１）の場合とは反対に、ケース本体７３の軸方向溝７３ｂに入力側ブロック７７の凸部７７ａを完全に嵌合することができず、上記（１），（２）の両方の場合で容易にしかも確実に誤組付と認識することができる。
【００１７】
更に、軸方向溝７３ｂの突起７３ｃと凸部７８ａの窪み７８ｂとが対応しない、即ち対向しないことも明らかに認識することができ、上記した上部幅Ｌ１，Ｌ２と合せて二重に誤組付の確認をより確実に行うことができる。
【００１８】
このように、図２（ａ）〜（ｃ）において、本発明の作動装置としてのデファレンシャルケース組立体５０は、駆動源に連結したリングギヤ７５（図１参照）の回転に伴って円周方向に移動する複数の入力側ブロック７７，７８と、これらの入力側ブロック７７，７８を相対滑り可能に挟み込むとともに各ブロック７７，７８との摩擦力で独立して回転することで出力側の差動を発生させる２つの出力側カム８１，８２（図１参照）とを備えたデファレンシャルケース組立体５０において、入力側ブロック７７，７８を複数種類で構成し、これらの入力側ブロック７７，７８に種類に応じて上部幅Ｌ１，Ｌ２を異ならせた凸部７７ａ，７８ａを設け、これらの凸部７７ａ，７８ａに嵌合する軸方向溝７３ａ，７３ｂをリングギヤ７５側に設けたことを特徴とする。

従って、誤組付による再組付等の無駄な工数が発生せず、生産性を向上させることができる。
【００２０】
尚、本発明では、図２（ｂ），（ｃ）で説明したように、凸部７７ａ，７８ａの上部幅Ｌ１、Ｌ２を、径方向に直角な方向の幅としたが、要は異なる種類の入力側ブロック７７，７８で、凸部の寸法を異ならせて別なものが結合できない形状にすればよい。
【００２１】

BACKGROUND OF THE INVENTION
The present invention relates to a differential device suitable for preventing erroneous assembly.
[0002]
[Prior art]
As a differential device that absorbs the rotational speed difference between wheels such as a four-wheeled vehicle and distributes the driving torque to each wheel, for example, Japanese Unexamined Patent Publication No. 8-500659 “Differential Mechanism” is known.
[0003]

When assembling the cam follower 28 in the input housing 11, the drive dog 36 with and without the groove 36 a is alternately arranged in the circumferential direction two by two.
[0004]
[Problems to be solved by the invention]
In the above technique, when the cam follower 28 is assembled in the input housing 11 and when the assembly is confirmed, the presence or absence of the groove 36a is visually checked. It is possible to assemble.
As a countermeasure, it is possible to confirm the erroneous assembly by performing a full number of operation tests after the differential mechanism is completed. However, there is an inconvenience that the number of work steps increases and the productivity is lowered.
[0005]
Therefore, an object of the present invention is to provide a differential device that can prevent erroneous assembly more reliably.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a plurality of input-side blocks that move in the circumferential direction as the differential case connected to the drive source rotates, and these input-side blocks are sandwiched so as to be relatively slidable. In the differential device having two output side cams that generate the output side differential by rotating independently by the frictional force between the input side block and the input side block. Protrusions with different widths according to the types are provided, and recesses that are respectively fitted to these protrusions are provided on the differential case side so that the widths differ according to the type of the input side block , and a plurality of types of the input side One of the blocks has a dent in the convex part, the concave part that fits into this convex part has a protrusion corresponding to the dent, there are two types of width of the convex part, and there is a dent on the tip surface of the narrow convex part This is provided When a protrusion is provided on the bottom of the concave portion that fits into the concave portion and the width of the concave portion that fits into the convex portion attempts to fit the other convex portion into the concave portion, the bottom of the concave portion and the other convex portion It is characterized in that a gap with the tip surface of the first portion is formed and the projection of the concave portion is formed smaller than the width of the other convex portion so as not to interfere with the tip surface of the other convex portion .
[0007]
An input side block having a convex portion with a width matching a concave portion provided on the differential case side can be coupled to the differential case side.
An input side block having a convex portion with a width that does not match the concave portion provided on the differential case side cannot be coupled to the differential case side.
Therefore, erroneous assembly of the input side block to the differential case side can be prevented.
[0008]
In addition, it can be clearly recognized that the projections of the recesses do not correspond to the depressions of the projections, that is, do not face each other. This is combined with the difference in the width of the projections depending on the type of the input side block. It is possible to check for incorrect assembly more reliably.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings. The drawings are viewed in the direction of the reference numerals.
FIG. 1 is an exploded perspective view of a differential device according to the present invention, and a differential case assembly 50 as an operating device includes a differential case 71 and a storage component 72 stored in the differential case 71.
[0010]
The differential case 71 includes a case main body 73 as a cylindrical differential case, and a cap 75 with a ring gear in which a ring gear 75a is integrally formed with a cap portion (described later) attached to one opening of the case main body 73.
[0011]
The storage component 72 is coupled to the differential case 71 to rotate integrally with two types of input-side blocks 77 (... indicates a plurality, the same applies hereinafter), 78 ..., and these input-side blocks 77 ..., 78... Are interposed between the left and right output cams 81 and 82 as output side cams that can be rotated independently of each other by a frictional force with each block, and the left and right output side cams 81. It consists of adjacent thrust bearings 83, 83, thrust washers 84, 84, and a disc spring 85. The thrust bearings 83 and 83 may be omitted.
[0012]
FIG. 2 is a sectional view of the differential according to the present invention in an assembled state.
The differential case assembly 50 includes a thrust washer 84, a thrust bearing 83, a right output side cam 82, input side blocks 77, 78,..., A left output side cam 81, a thrust bearing arranged in the circumferential direction. 83, a thrust washer 84 and a disc spring 85 are stacked and housed, and a cap 75 with a ring gear is attached to the case body 73 with bolts 87 (only one is shown).
[0013]
FIGS. 3A to 3C are explanatory views for explaining the input side block of the differential device according to the present invention.
(A) shows the state which removed the cap 75 with a ring gear (refer FIG. 1) and the left output side cam 81 (refer FIG. 1) from the assembled differential case assembly 50. FIG.
The case main body 73 is formed by alternately forming two axial grooves 73a... 73b... As recesses parallel to the rotation axis (the axis extending in the front and back direction in the figure) of the differential case assembly 50 on the inner peripheral surface. It is.
The input side blocks 77 ..., 78 ... are provided with convex portions 77a ..., 78a ..., respectively, and these convex portions 77a ..., 78a ... are fitted in the axial grooves 73a ..., 73b ... of the case body 73, respectively. The two are arranged alternately in the circumferential direction.
[0014]
(B) is a principal part enlarged view of (a) which shows the case main body 73 and the input side block 77 which meshes with this case main body 73. FIG.
The axial groove 73a is a substantially trapezoidal groove, and the convex portion 77a is a portion substantially similar to the shape of the axial groove 73a. Here, the upper width as the width of the convex portion 77a is L1.
[0015]
(C) is an enlarged view of a main part of (a) showing a case main body 73 and an input side block 78 meshing with the case main body 73.
The axial groove 73b is a substantially trapezoidal groove, and the convex part 78a is a portion substantially similar to the shape of the axial groove 73b. Here, assuming that the upper width as the width of the convex portion 78a is L2, the upper width L2 is different from the upper width L1 shown in (b), that is, L1 ≠ L2.
In (b) and (c), L1> L2, but L1 <L2.
The axial groove 73b has a protrusion 73c on the groove bottom, and the convex part 78a has a recess 78b corresponding to the protrusion 73c on the upper surface.
[0016]
Next, incorrect assembly of the input side block of the differential device will be described.
4 (a) and 4 (b) are operation diagrams for explaining erroneous assembly of the input side block of the differential device according to the present invention.
In (a), originally, the convex portion 77a of the input side block 77 is fitted into the axial groove 73a of the case main body 73, and the convex portion 78a of the input side block 78 is fitted to the axial groove 73b of the case main body 73. However, (1) the convex portion 78a of the input side block 78 is erroneously fitted into the axial groove 73a, and (2) the convex portion of the input side block 77 is inserted into the axial groove 73b of the case body 73. When trying to fit the portion 77a, as shown in (b), in the case of (1) above, the upper width L2 of the input side block 78 is smaller than the upper width L1 of the input side block 77. A large gap is generated between the axial groove 73a of the case body 73 and the convex portion 78a of the input side block 78. In the case of (2), the axis of the case body 73 is opposite to the case of (1). Input side block in direction groove 73b 7 of the convex portion 77a can not be completely fitted, the (1), can be recognized easily and reliably erroneous assembly in the case of both (2).
[0017]
Further, it can be clearly recognized that the protrusion 73c of the axial groove 73b and the recess 78b of the convex part 78a do not correspond to each other, that is, do not face each other. Can be confirmed more reliably.
[0018]
As described above, in FIGS. 2A to 2C, the differential case assembly 50 as the actuating device of the present invention moves in the circumferential direction along with the rotation of the ring gear 75 (see FIG. 1) connected to the drive source. A plurality of input-side blocks 77 and 78 that move, and these input-side blocks 77 and 78 are sandwiched so as to be relatively slidable, and are rotated independently by the frictional force with each of the blocks 77 and 78, so that the differential on the output side can be obtained. In the differential case assembly 50 having two output side cams 81 and 82 (see FIG. 1) to be generated, the input side blocks 77 and 78 are composed of a plurality of types, and these input side blocks 77 and 78 are classified into types. Accordingly, convex portions 77a and 78a having different upper widths L1 and L2 are provided, and axial grooves 73a and 73b that fit into the convex portions 77a and 78a are provided on the ring gear 75 side. It is characterized in.
[0019]
With the above configuration, erroneous assembly of the input side blocks 77 and 78 to the ring gear 75 side can be prevented more reliably.
Therefore, useless man-hours such as reassembly due to incorrect assembly do not occur, and productivity can be improved.
[0020]
In the present invention, as described with reference to FIGS. 2B and 2C, the upper widths L1 and L2 of the convex portions 77a and 78a are widths in the direction perpendicular to the radial direction. In the input side blocks 77 and 78, the dimensions of the convex portions may be made different so that another cannot be coupled.
[0021]
【The invention's effect】
The present invention exhibits the following effects by the above configuration.
The actuating device according to claim 1 comprises a plurality of types of input side blocks, provided with convex portions having different widths according to the types of the input side blocks, and inputs concave portions respectively fitted to these convex portions. Since it is provided on the differential case side so that the width varies depending on the type of the side block, it is possible to more reliably prevent erroneous assembly of the input side block on the differential case side.
Therefore, useless man-hours such as reassembly due to incorrect assembly do not occur, and productivity can be improved.
[0022]
In addition, one of the plural types of input side blocks has a recess in the convex portion, and the concave portion that fits into the convex portion has a projection corresponding to the concave portion, so the projection in the concave portion does not correspond to the concave in the convex portion. In other words, it can be clearly recognized that they do not face each other, and in addition to the fact that the width of the convex portion is varied according to the type of the input side block, it is possible to more surely confirm the double assembling more reliably. .
